Another object of the invention is to provide a fluid operated vacuum device in which a single 39 member serves both to conduct operating fluid into the device and to controladmission of the Another object is to provide a fluid operated vacuum device for use with a standard valved air chuck'in which the chuck valve serves as a control valve to control admission of operating fluid to the device.

Other objects and advantages of the invention including novel combinations and particular features will be apparent from the following description of the accompanying drawing in which the single figure is a central section of an air operated vacuum cleaner embodying the invention.

The illustrated cleaner comprises a conduit 10 of Venturi formation carrying at one end a cleaner nozzle lZ-of any desired formation. A filter bag M of suitable construction may be secured to the opposite end of the conduit M to receive and retain dirt picked up by the nozzle l2.

Air under pressure is supplied to the conduit through a tube l6 slidably mountedtransversely of the conduit and having therein an outlet orifice 98 facing away from the nozzle l2. One end of the tube i6 is closed and terminates in a head. or button to be engaged by an operators thumb, a pin 22 carried by the conduit I0 being slidable in a bore in the head to prevent turning thereof and of the tube IS.

The opposite end of the tube is open, preferably being formed with a series of air admitting slots, and extends through a suitable air nipple 24. The nipple 24 is formed for sealing engagement with a conventional air chuck 26 and is provided with a clamp 28 to hold the chuck securely thereon. The chuck is provided with an inwardly opening check valve 30 normally held closed by air pressure and which is aimed with the tube fit when'the chuck is secured to the nipple.

The parts are shown in released position with g the valve 3|! closed and no air being admitted to the tube 56. To operate the cleaner, the button --2'0l -,i's engaged to press the tube l6 down to open valve 30 and admit air to the tube It to flow out through the opening opening creates a partial vacuum in the nozzle [8.

l 2 so that dirt will be picked up and carried into the bag Hi. When the button 20 is released the valve 30 will again close.

While one embodiment of the invention has been illustrated and described in detail it will be 5 understood that many other embodiments might be devised and it is not intended to limit the scope of the invention to the form shown or otherwise than by the terms of the appended claims. 4 What is claimed is: m 1. A fluid operated vacuum device comprising a conduit, a tubular member extending transversely of said conduit and slidable relatively thereto and formed with a transverse outlet opening within the conduit, and means including a valve secured 15 to said conduit for supplying fluid to said tubular'member said valve being disposed in the path of said tubular member to be operated by sliding movement thereof.

2. A fluid operated vacuum device comprising a conduit having an inlet at onelend, a tubular member extending transversely across said conduit and slidable relative thereto and having an air outlet orifice facing away from said inlet, and means including a valve exterior to said conduit for supplying fluid to said tubular member, said valve arranged to be operated by sliding of the member.

3. A'fiuid operated vacuum device comprising a conduit having an inlet at one end, a tubular member extending transversely across said conduit and slidable relative'thereto and having an air outlet orifice facing away from said inlet, means for preventing rotation of said tubular member, and means including a valve exterior to said conduit for supplying fluid to said tubularmember, said valve arranged to be operated by sliding of the member.

4. An air operated vacuum device comprising a conduit having an air inlet at one end, a tubular member slidably mounted transversely of the conduit and extending completely thereacross, one

end of said member being closed and the other end being open and there being an outlet opening intermediate the ends of said member within the conduit, means including a valve exterior to the conduit for supplying fluid to the tubular member, the open end of said member being adapted to operate the'valve to control admission of air to the member.

, 5. In combination with an air chuck having a valve therein, a vacuum conduit, a nipple carried by said conduit for sealing engagement with the air chuck, a tube slidable transversely of the conduit and extending through said nipple, said tube having an air outlet opening intermediate said nipple, a tube slidably carried by the 0011- its ends within said conduit and one end of said duit transversely thereof with one end extending tube engaging said valve to control it. through the nipple, said one end being engageable 6. In combination with an air chuck having a with said valve to open it, and said tube being 5 valve therein, a vacuum conduit, anipplecarried formed with an air outlet opening within the 6 by said conduit for sealing engagement with the conduit. air chuck, means for clamping the air chuck to GEORGE 0.
